TIRE FOR BICYCLES.

SPECIFICATION forming part of Letters Patent No. 582,172, dated May 11, 1897. Application filed January 23, 1896. Serial No. 576,668. (No model.)

To r/JZ 7117mm iiuu concern:

Be it known that I, CHARLES F. BROWNE, a

' citizen of the United States. residing at \Vestfield, in the county of Hampden and State of Massachusetts, have invented certain new and useful Improvements in Tires for Bicyto make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention has relation to improvements in pneumatic tires for bicycles or other vehicles; and it consists in the novel construction and arrangement of parts, as will be hereinafter described, and particularly pointed out in the claims.

In the accompanying drawings, Figure 1 is a side View of my invention, partly in section. Fig. 2 is an enlarged detail view. Fig. 3 is a transverse section. Fig. 4 is a transverse section showing the tire applied to a felly or rim. Fig. 5 is an inside viewof the telly or rim, showing the slide. Fig. 6 is a partial section of Fig. 4:, showing the lacing and cord for holding rings'to the rim; and Fig. 7 is a detail view of the tire, showing the flaps.

Referring to the drawings, the letter A represents a surrounding inflating-tube having formed therewith at suitable intervals thereon a series of independent projections h, each being provided with a button I) on the upper extremity, as shown in Fig. 3, for a purpose to be presently explained.

The letter O designates bags, made in ob-- long or barrel-shape form, saidloags being arranged side by side, as shown in Fig. 1. These bags are each provided with elongated valves B, formed therewith and being virtually the necks of the bags. Each of these valves where they merge into the bags is provided with a the projections 11 of said tube allow free passage of air through the valves 13 and into the bags. This action is accomplished by the pressure of air forced through the pump-tube E. The valves B are made of tl1in-rubber tubing rolled flat and are constructed of sufficient length so that their upper ends will curve, as shown at c, and bear against the inner upper surface of the bags, so that the airpressure developed by the inflated bagswill immediately close the valves on the removal of the pump from the tube E, thereby preventing the air contained in the bags from returning to the inflating-tube. Each bag is to be of such capacity so as to hold enough of air so that they will abut one against the other, thereby leaving no space between. them.

In case of puncture of a bag and consequent escape of air therefrom the bags next on opposite sides thereof close up and take the place of the punctured bag, the other bags in the tire also closing in turn one against the other, whereby the punctured bag is not missed from the tire. By applying the pump to the inflating-tube the bags may be further stretched,'so as to more readily fill the space of one or more punctured bags, thus making the tire in as good condition as before puncturing. The letter D denotes the outside cover, made of any suitable material, said cover inclosing the bags and inflating-tube. The meeting ends of the cover are provided With a series of flaps or sections f, which are lined with canvas to prevent stretching. The object of forming these sections in such manner is to prevent puckering and also to readil-y facilitate the removal of a punctured bag and substituting a new one without wholly removing the cover. Rings dare attached in any suitable manner to the sections f. Cords pass through these rings and are secured in an opening e of the rim, said opening being closed by a slide F in said rim.

Having described my invention, what I claim is l. A vehicle-tire having inclosed therein a series of bags, each having a valve with their upper ends curved and adapted to bear against the inner upper surfaces of the bags, whereby when one of the series of said bags is punctured the adjacent bags expand and close the valve of the punctured bag and thus prevent the leakage of air substantially as and for the purpose set forth.

2. A vehicle-tire having an inflating-tube r, With a series of projections, provided with buttons thereon, and bags with integral valves and rings, said rings being forced over the buttons, a cover for inolosing said inflatingtube, and bags, the cover being provided with a series of canvas flaps or sections at its ineet- IO ing edges and lacings connected to said edges,

substantially as specified.

In testimony whereof I affix my signature in presence of two Witnesses.

CHARLES F. BROWNE.
